FLUIDIZED SANDBED BIOFILTER

A fluidized Sandbed Biofilter is a high-efficiency filter that will replace the traditional bio-trough system with a much smaller footprint. It uses anaerobic denitrification technology to treat ammonia nitrogen in water. Calcified coral sand is used as its filter media, with a contact area of up to 20000 24000m2/m3 (depending on the size of the selected coral sand), and 1kg coral sand can handle 16g of ammonia (NH4) per 24 hours on average. Compared with traditional biochemical denitrification equipment, it not only occupies a smaller area and consumes less power, but also greatly improves the efficiency of denitrification.

It is applicable for freshwater or seawater aquaculture.

Nitrification:    
1 Kg Filter media / 16 gram(NH3)/ 24 hour
1 kg Protein (Food)= 160 gram(NH4)
100 kg fish = 1 kg protein
10 kg Fluidized sand = 100 Kg fish (for stable effect, X 2-3times)

Features:

High efficiency

Small footprint

Low maintenance costs

Material:

LDPE and UPVC, standard UPVC pipeline connection.
